Command line RDF/N3 tool
<command> <options> <steps> [--with <more args> ]
options:
--pipe Don't store, just pipe out *
steps, in order left to right:
--rdf Input & Output ** in RDF/XML insead of n3 from now on
--n3 Input & Output in N3 from now on. (Default)
--rdf=flags Input & Output ** in RDF and set given RDF flags
--n3=flags Input & Output in N3 and set N3 flags
--ntriples Input & Output in NTriples (equiv --n3=usbpartane -bySubject -quiet)
--language=x Input & Output in "x" (rdf, n3, etc) --rdf same as: --language=rdf
--languageOptions=y --n3=sp same as: --language=n3 --languageOptions=sp
--ugly Store input and regurgitate, data only, fastest *
--bySubject Store input and regurgitate in subject order *
--no No output *
(default is to store and pretty print with anonymous nodes) *
--base=<uri> Set the base URI. Input or output is done as though theis were the document URI.
--closure=flags Control automatic lookup of identifiers (see below)
<uri> Load document. URI may be relative to current directory.
--apply=foo Read rules from foo, apply to store, adding conclusions to store
--patch=foo Read patches from foo, applying insertions and deletions to store
--filter=foo Read rules from foo, apply to store, REPLACING store with conclusions
--query=foo Read a N3QL query from foo, apply it to the store, and replace the store with its conclusions
--sparql=foo Read a SPARQL query from foo, apply it to the store, and replace the store with its conclusions
--rules Apply rules in store to store, adding conclusions to store
--think as -rules but continue until no more rule matches (or forever!)
--engine=otter use otter (in your $PATH) instead of llyn for linking, etc
--why Replace the store with an explanation of its contents
--why=u proof tries to be shorter
--mode=flags Set modus operandi for inference (see below)
--reify Replace the statements in the store with statements describing them.
--dereify Undo the effects of --reify
--flatten Reify only nested subexpressions (not top level) so that no {} remain.
--unflatten Undo the effects of --flatten
--think=foo as -apply=foo but continue until no more rule matches (or forever!)
--purge Remove from store any triple involving anything in class log:Chaff
--data Remove all except plain RDF triples (formulae, forAll, etc)
--strings Dump :s to stdout ordered by :k whereever { :k log:outputString :s }
--crypto Enable processing of crypto builtin functions. Requires python crypto.
--help print this message
--revision print CVS revision numbers of major modules
--chatty=50 Verbose debugging output of questionable use, range 0-99
--sparqlServer instead of outputting, start a SPARQL server on port 8000 of the store
--sparqlResults After sparql query, print in sparqlResults format instead of rdf
finally:
--with Pass any further arguments to the N3 store as os:argv values
* mutually exclusive
** doesn't work for complex cases :-/
Examples:
cwm --rdf foo.rdf --n3 --pipe Convert from rdf/xml to rdf/n3
cwm foo.n3 bar.n3 --think Combine data and find all deductions
cwm foo.n3 --flat --n3=spart
Mode flags affect inference extedning to the web:
r Needed to enable any remote stuff.
a When reading schema, also load rules pointed to by schema (requires r, s)
E Errors loading schemas of definitive documents are ignored
m Schemas and definitive documents laoded are merged into the meta knowledge
(otherwise they are consulted independently)
s Read the schema for any predicate in a query.
u Generate unique ids using a run-specific
Closure flags are set to cause the working formula to be automatically exapnded to
the closure under the operation of looking up:
s the subject of a statement added
p the predicate of a statement added
o the object of a statement added
t the object of an rdf:type statement added
i any owl:imports documents
r any doc:rules documents
E errors are ignored --- This is independant of --mode=E
n Normalize IRIs to URIs
e Smush together any nodes which are = (owl:sameAs)
See http://www.w3.org/2000/10/swap/doc/cwm for more documentation.
Setting the environment variable CWM_RDFLIB to 1 maked Cwm use rdflib to parse
rdf/xml files. Note that this requires rdflib.
Flags for N3 output are as follows:-
a Anonymous nodes should be output using the _: convention (p flag or not).
d Don't use default namespace (empty prefix)
c Comments added at top about version and base URI used.
e escape literals --- use \u notation
g Suppress => shothand for log:implies
i Use identifiers from store - don't regen on output
l List syntax suppression. Don't use (..)
n No numeric syntax - use strings typed with ^^ syntax
p Prefix suppression - don't use them, always URIs in <> instead of qnames.
r Relative URI suppression. Always use absolute URIs.
s Subject must be explicit for every statement. Don't use ";" shorthand.
t "=" and "()" special syntax should be suppresed.
u Use \u for unicode escaping in URIs instead of utf-8 %XX
v Use "this log:forAll" for @forAll, and "this log:forAll" for "@forSome".
/ If namespace has no # in it, assume it ends at the last slash if outputting.
Flags for N3 input:
B Turn any blank node into a existentially qualified explicitly named node.
Flags to control RDF/XML output (after --rdf=) areas follows:
b - Don't use nodeIDs for Bnodes
c - Don't use elements as class names
d - Default namespace supressed.
l - Don't use RDF collection syntax for lists
r - Relative URI suppression. Always use absolute URIs.
z - Allow relative URIs for namespaces
Flags to control RDF/XML INPUT (after --rdf=) follow:
S - Strict spec. Unknown parse type treated as Literal instead of error.
T - take foreign XML as transparent and parse any RDF in it
(default it is to ignore unless rdf:RDF at top level)
L - If non-rdf attributes have no namespace prefix, assume in local <#> namespace
D - Assume default namespace decalred as local document is assume xmlns=""
R - Do not require an outer <rdf:RDF>, treating the file as RDF content (opposite of T)
Note: The parser (sax2rdf) does not support reification, bagIds, or parseType=Literal.
It does support the rest of RDF inc. datatypes, xml:lang, and nodeIds.
